Terms of the Trade: What Is a Chop Saw?

A chop saw cutting metal.

Chop saws often get compared to miter saws, but the main difference is that chop saws only cut in 90 degree angles, while a miter saw can rotate and cut at an angle. Chop saws are also larger than miter saws, and can cut through just about anything. While most DIYers can get by with just a miter saw, a chop saw will come in handy if you're building a house or otherwise cutting large pieces of lumber.
